Description

Technical Field

[0001] This utility model relates to the field of airflow nozzle technology, and in particular to a noise reduction device for a twisted airflow nozzle. Background Technology

[0002] Most existing airflow nozzles are quite noisy. High noise levels can not only damage the hearing of workers, but also cause negative emotions such as irritability and anxiety, reducing work efficiency and quality.

[0003] Therefore, there is an urgent need to provide a noise reduction device for twisted airflow nozzles to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a twisted airflow nozzle noise reduction device.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: a twisted airflow nozzle noise reduction device, comprising a connecting pipe, a connecting plate fixedly connected to the top of the connecting pipe, an installation pipe fixedly connected to the top of the connecting plate, a nozzle fixedly connected to the top of the installation pipe, a plurality of first connecting rods fixedly connected to the top of the connecting plate, an installation plate fixedly connected between the tops of the plurality of first connecting rods, a plurality of second connecting rods and a fixing column fixedly connected to the top of the installation plate, a connecting plate fixedly connected between the tops of the plurality of second connecting rods and the fixing column, a noise reduction component installed on the top of the connecting plate, and an adjustment component installed inside the connecting pipe.

[0006] The present invention is further configured such that: the bottom of the inner wall of the connecting pipe and one side of the inner wall of the nozzle are both provided with threaded lines.

[0007] Through the above technical solution, the design of the threaded wire can effectively prevent gas leakage when the connecting pipe and nozzle are connected to external parts. When the twisted airflow nozzle is working, the gas usually flows under high pressure. Good sealing performance can ensure that the gas flows along the predetermined path and improve work efficiency.

[0008] The present invention is further configured such that a noise reduction ring is fixedly connected to the other side of the inner wall of the nozzle, and the noise reduction ring is made of silicone.

[0009] Through the above technical solution, silicone material has good damping characteristics, which can reduce the transmission of vibration. During the operation of the twisted airflow nozzle, the impact and vibration of the airflow will generate noise. The silicone noise reduction ring can reduce the amplitude of vibration through damping, thereby reducing the generation of noise.

[0010] The present invention is further configured such that: the noise reduction component includes a hydraulic cylinder installed on the top of the connecting plate, a push rod is fixedly connected to the bottom of the hydraulic cylinder, a noise reduction plate is fixedly connected to the bottom of the push rod, and noise reduction cotton is fixedly connected to the bottom of the noise reduction plate.

[0011] The above technical solution first activates the hydraulic cylinder, causing the push rod to move downwards. Then, the push rod moves the noise reduction plate synchronously, and at the same time, the noise reduction plate moves the noise reduction cotton synchronously until the bottom of the noise reduction cotton is in contact with the outer wall of the nozzle.

[0012] The present invention is further configured such that the bottom of the noise-reducing cotton is tightly fitted to the outer wall of the nozzle, and the noise-reducing cotton is made of rubber.

[0013] Through the above technical solution, the rubber noise-reducing cotton has good sound absorption characteristics. It can effectively absorb the noise energy generated when the nozzle is working and reduce the propagation of noise. At the same time, the rubber noise-reducing cotton that is tightly attached to the inner wall of the nozzle can form a barrier to prevent the noise from spreading to the surrounding environment, thereby significantly reducing the noise level.

[0014] The present invention is further configured such that: the adjusting component includes a fixed plate fixedly connected inside the connecting pipe, a hydraulic rod is installed on the top of the fixed plate, a limit block is fixedly connected to the top of the hydraulic rod, an adjusting groove is provided on the inner wall of the nozzle, and an adjusting plate is slidably connected to the inner wall of the adjusting groove.

[0015] The above technical solution involves first activating the hydraulic rod, which causes the limiting block to move upward, thereby confining the adjusting plate to one side of the adjusting groove. When pressure adjustment is required, the hydraulic rod is simply retracted, which causes the limiting block to move synchronously. Then, the adjusting plate is manually pushed to the other side of the adjusting groove, and finally the limiting block is reset, thus achieving the adjustment effect.

[0016] The present invention is further configured such that the limiting block penetrates the outer wall of the nozzle, and the limiting block is tightly fitted with the through groove.

[0017] The above technical solution can precisely limit the movement range of the regulating plate, thereby achieving accurate control of air pressure. Furthermore, the tightly fitting limit block can ensure that the regulating plate moves within the set range, keeping the air pressure in a relatively stable state and improving the reliability during operation.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By setting up a noise reduction component, this utility model can effectively reduce noise levels. At the same time, it can also improve the operator's alertness and reduce operational errors and accidents caused by lack of concentration.

[0020] 2. This utility model reduces noise intensity by setting a noise reduction ring, which is usually made of a material with good sound absorption properties and can absorb a portion of the noise energy, converting sound energy into heat energy or other forms of energy.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 4A noise reduction device for a twisted airflow nozzle includes a connecting pipe 1, with a connecting disc 2 fixedly connected to the top of the connecting pipe 1. Threads 101 are provided on the bottom of the inner wall of the connecting pipe 1 and one side of the inner wall of the nozzle 4. The design of the threaded lines 101 effectively prevents gas leakage when the connecting pipe 1 and the nozzle 4 are connected to external parts. During operation of the twisted airflow nozzle, the gas typically flows under high pressure; good sealing performance ensures that the gas flows along a predetermined path, improving work efficiency. An installation pipe 3 is fixedly connected to the top of the connecting disc 2, and a nozzle 4 is fixedly connected to the top of the installation pipe 3. A noise reduction device is fixedly connected to the other side of the inner wall of the nozzle 4. The noise reduction ring 401 is made of silicone. Silicone material has good damping properties and can reduce the transmission of vibration. During the operation of the twisted airflow nozzle, the impact and vibration of the airflow will generate noise. The silicone noise reduction ring 401 can reduce the amplitude of vibration through damping, thereby reducing the generation of noise. Multiple first connecting rods 5 are fixedly connected to the top of the connecting plate 2. A mounting plate 6 is fixedly connected between the tops of the multiple first connecting rods 5. Multiple second connecting rods 7 and a fixing column 9 are fixedly connected to the top of the mounting plate 6. A connecting plate 8 is fixedly connected between the tops of the multiple second connecting rods 7 and the fixing column 9.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, a noise reduction component 10 is installed on the top of the connecting plate 8. The noise reduction component 10 includes a hydraulic cylinder 1001 installed on the top of the connecting plate 8. A push rod 1002 is fixedly connected to the bottom of the hydraulic cylinder 1001. A noise reduction plate 1003 is fixedly connected to the bottom of the push rod 1002. Noise reduction cotton 1004 is fixedly connected to the bottom of the noise reduction plate 1003. First, the hydraulic cylinder 1001 is activated, causing the hydraulic cylinder 1001 to drive the push rod 1002 to move downward. Then, the push rod 1002 will drive the noise reduction plate 1003 to move synchronously. At the same time, the noise reduction plate 1003 will... The noise-reducing cotton 1004 moves synchronously until its bottom is in close contact with the outer wall of the nozzle 4. The noise-reducing cotton 1004 is made of rubber; this rubber material has excellent sound absorption properties, effectively absorbing the noise energy generated by the nozzle 4 during operation and reducing noise propagation. Simultaneously, the rubber noise-reducing cotton 1004, tightly adhering to the inner wall of the nozzle 4, forms a barrier, preventing noise from propagating to the surrounding environment, thereby significantly reducing the noise level.

[0029] like Figure 2 and Figure 4As shown, an adjustment assembly 11 is installed inside the connecting pipe 1. The adjustment assembly 11 includes a fixed plate 1101 fixedly connected inside the connecting pipe 1. A hydraulic rod 1102 is installed on the top of the fixed plate 1101. A limit block 1103 is fixedly connected to the top of the hydraulic rod 1102. An adjustment groove 1104 is opened on the inner wall of the nozzle 4. An adjustment plate 1105 is slidably connected to the inner wall of the adjustment groove 1104. First, the hydraulic rod 1102 is activated, causing the hydraulic rod 1102 to drive the limit block 1103 to move upward, thereby restricting the adjustment plate 1105 to one side of the inner wall of the adjustment groove 1104. When it is necessary to adjust the pressure, it is only necessary to adjust the hydraulic rod 1102. 02 retracts, which drives the limiting block 1103 to move synchronously. Then, the adjusting plate 1105 is pushed to the other side of the inner wall of the adjusting groove 1104 by manual means. Finally, the limiting block 1103 is reset, thereby achieving the adjustment effect. The limiting block 1103 penetrates the outer wall of the nozzle 4 and fits tightly with the through groove. It can accurately limit the movement range of the adjusting plate 1105, thereby achieving precise control of air pressure. The tightly fitted limiting block 1103 can ensure that the adjusting plate 1105 moves within the set range, keeping the air pressure in a relatively stable state and improving the reliability of the working process.

[0030] In use, this invention first activates the hydraulic cylinder 1001, causing it to drive the push rod 1002 downwards. The push rod 1002 then drives the noise-reducing plate 1003 to move synchronously, while the noise-reducing plate 1003 drives the noise-reducing cotton 1004 to move synchronously until the bottom of the noise-reducing cotton 1004 is in contact with the outer wall of the nozzle 4. Next, the hydraulic rod 1102 is activated, causing it to drive the limiting block 1103 upwards, thus restricting the adjusting plate 1105 to one side of the inner wall of the adjusting groove 1104. When pressure adjustment is needed, simply retract the hydraulic rod 1102 to drive the limiting block 1103 to move synchronously. Then, manually push the adjusting plate 1105 to the other side of the inner wall of the adjusting groove 1104. Finally, reset the limiting block 1103 to achieve the adjustment effect.
